Definitions

  • the present invention relates to an automatic disk cassette changer which automatically inserts/removes a disk cassette into/from an optical disk unit and automatically substitutes specified disk cassettes for each other.
  • a conventional disk changer permits a round and light weight disk to be carried comparatively accurately by holding part of the disk with a chuck of simple configuration; but, carrying a square and heavy-weight disk contained in a cassette requires a heavy-weight chuck of complicated configuration in order to assure good accuracy.
  • Another object of the invention is to provide an automatic disk cassette changer which permits disk cassettes to be accurately positioned for information recording/reading operations.
  • an automatic disk cassette changer comprising:
  • the automatic disk cassette changer of the invention can thus automatically insert/remove a disk cassette into/from an optical disk unit and automatically substitutes specified disks for each other the arrangement being such that a disk cassette containing disks can also be carried automatically to and from the store, achieving the above purposes.
  • the invention relating to such an automatic disk replacement unit is characterised by another feature that a disk cassette containing disks, which ⁇ is caught completely in the carrying frame, is carried out.
  • Figure 2 shows a data processing system, in which one embodiment of the automatic disk cassette changer of the invention may be utilised.
  • Numeral 1 refers to a main controller.
  • Main controller 1 is connected to a reader 2, an optical disk read/write unit 3, an automatic disk cassette changer 4 incorporating such optical disk unit 3, a keyboard 5, a display device 6, a recorder 7, and a floppy disk unit 8, being capable of performing various types of image information and data processing functions.
  • Reader 2 which for example, is composed of a two-dimensional scanner, scans over a document in a two dimensional manner using a laser beam to generate electrical signals representing image information on the document.
  • Optical disk read/write unit 3 incorporated in changer 4 records document image information read in reader 2 and supplied through main controller 1 onto an optical disk 9 ( Figure 3), described subsequently.
  • Keyboard 5 is used to enter particular retrieval codes corresponding to document image information, and operation instructions.

  • top frame 16 of upper storage rack 15a is equipped with a third guide 50 used to guide the top edge of the disk cassette 10 when it is inserted.
  • the wall 15a' of upper storage rack 15a is provided with a solenoid-operated detent device 52 having a movable stop 51, which stops and catches along with guide roller 48 the inserted disk cassette 10.
  • stop 51 is withdrawn when solenoid 52 is activated, enabling disk cassette 10 to be released for rearward movement.
  • disk cassette 10 is placed on guide roller 48 with its top edge in third guide 50, the standing disk cassette 10 is moved along slide plate 23, and is guided by guide 50, projection 38 on slide plate 23, and the projection 37 of first guide 21.
  • Disk cassette 10, when it is inserted completely onto slide plate 23, is seated between guide roller 48 and stop 51, and thereby is located on slide plate 23 in the initial position. Note that in the initial position, cassette 10 projects beyond the end of slide plate 23, as shown in Fig. 7.

  • the cassette 10 is inserted securely, when third and fourth detectors 42 and 43 are both turned on.
  • fourth detector 43 if the cassette is inserted backwards, fourth detector 43 is turned on, while third detector 42 is turned.off since detecting bar 44 is not pushed. This indicates that the cassette 10 has not been inserted in the proper direction. If the cassette has been inserted in the proper direction, stop 51 is released, but if it has been inserted improperly, stop 51 is not released.
  • stepping motor 24 operates to drive slide plate 23 toward upper storage rack 15a with disk cassette 10 supported as shown in Figure 9.
  • disk cassette 10 loaded on slide plate 23 is oriented in the same state as cassettes already loaded in upper storage rack 15a.
  • Use of motor 24 as the drive source for slide plate 23 provides high stop position accuracy and permits slide plate 23 to be fixed in a stop position as shown in Fig. 11 by the self- holding force of the motor.
  • cassette handler 14 may be handled by cassette handler 14 in the same manner as cassettes already stored in storage unit 13.

  • Lower guide rail 86 which is longer than upper guide rail 85, is provided with a sliding pawl 88 which engages recess 53 (Fig. 15) of disk cassette 10 whereby the cassette can be pulled into position in carrying frame 72 and can be fed therefrom.
  • Pawl 88 is coupled to a belt 89, which is entrained on rollers 90 fitted at both ends of the lower guide rail 86.
  • the rear roller 90 is coupled by belt 93 to a pulley 92 driven by a stepping motor 91 fitted on frame 84.
  • Positive and negative rotation of stepping motor 91 moves the sliding pawl 88 along guide rail 86.
  • the tip of lower guide rail 86 is equipped with a pair of guide rollers 94, 94 to guide the edge of a disk cassette 10 when it is caught and fed.

  • sliding pawl 88 is driven to the right to pull the disk cassette into carrying frame 72. Feeding the disk cassette 10. from the carry- 5 ing frame back into the storage rack 15a, 15b is accomplished by reversing the above sequence of operations.
  • 3 to carrying frame 72 is identical to taking disk cassette 10 from storage racks 15a, 15b to carrying frame 72, except that carrying frame 72 is oriented horizontally instead of vertically, as shown in Figures 19A through 19C.
  • Carrying device 14 is so constructed, where the initial position (carry start position) corresponds to the central position in the Y direction of storage racks 15a, 15b (direction of stacking disk cassettes), takes out disk cassette 10 as moving it to the horizontal direction.
  • Carrying frame 72 is turned at the initial position, and is also moved to the Z direction.
  • Carrying device 14 loads optical disk unit 3 with a disk cassette 10 carried in by carrying in and out device 12, turning carrying frame 1 72 to the correct position on the basis of information on one side of disk 9, read by optical disk unit 3, which gives identification of the side A or B, and accommodates disk cassette 10 in storage rack 15a or 15b in the same direction as the other disk cassettes.
  • Fig. 20 schematically illustrates the control circuits employed in operating the various motors and solenoid devices to achieve the above described system functions.
  • control section 100 feeds a drive signal to the stopping device 52 consisting of the rotary solenoid 51, causing the solenoid to retract the stop arm from the path of the disk cassette 10, permitting transport thereof.

  • the control section 100 then supplies a drive signal of a predetermined pulse number to the stepping motor 91 to drive the motor 91 until the sliding pawl 88 locked in the recess 53 of the disk cassette 10 is brought to a position out of the carrying frame 72. With this movement of the sliding pawl 88, the disk cassette 10 is taken out of the carrying frame 72 and inserted in the vacant space in the rack 15a. At this time, the first detector 20 detects that the cassette 10 is inserted in the rack 15a and supplies a detection signal to the control section 100.
